SARS-CoV-2 is an enveloped positive-sense RNA virus and it's the 7th coronavirus which can infect human causing disease ranging from mild common cold, fever, dry cough, fatigue, shortness of breath and severe respiratory failure.[1]

SARS-CoV-2 testing may be incorporated as part of a comprehensive approach to reducing transmission. Symptom screening, testing, and contact tracing are strategies to identify people infected with SARS-CoV-2 so that actions can be taken to slow and stop the spread of the virus.[2]

Various categories of in vitro diagnostic tests are used to detect SARS-CoV-2: Viral tests, including nucleic acid amplification tests (NAATs) and antigen tests are used as diagnostic tests to detect infection with SARS-CoV-2 which is important to patient isolation, management and treatment. Antibody tests (Serology tests) are widely used in the previous SARS-CoV-2 infection detection and aid in the diagnosis of current SARS-CoV-2 infection combined with PCR, clinical symptoms, risk factors or a chest CT scan.
